the process of becoming easily hurt or affected by exposure to or the possibility of being exposed to a hazardous substance.
Immune process whereby individuals become hypersensitive to substances, pollen, dandruff, or other agents that make them develop a potentially harmful allergy when they are subsequently exposed to the sensitizing material (allergen). RT allergy, hypersensitivity.
Enhancement of the strength of a reflexive response produced by the presentation of a noxious stimulus.
An increased response to a drug caused by repeated administration. Sensitization is most commonly seen in some responses to stimulants.
An increase in behavioral response following exposure to a threatening stimulus. go to glossary index
The development of a hypersensitive or allergic reaction upon reexposure to a substance. The reaction may be immediate or delayed and may be of short-term or chronic duration.
state of immune response reaction in which exposure to a material elicits an immune or allergic response.
Enhancement of response to most stimuli following exposure to a significant signal.; Related Terms: Pseudoconditioning; Example: We blink everytime a puff of air is blown onto our cornea. A subsequent sound will also produce an eye blink even though UCS (air puff) and CS (tone) had never been paired with each other.
A hypersensitive reaction that occurs with repeated exposure to an allergen.
Exposure to a foreign substance resulting in an allergic response
Development, over time, of an allergic reaction to a substance
Enhancement of a response by an organism that is produced by delivering a strong, generally noxious, stimulus. A neuron becomes more excitable or responsive; it may respond more intensely to naturally occurring stimuli, either peripherally (in the viscera) or centrally (in the brain).
Sensitization is a type of allergic reaction in which the affected person becomes increasingly sensitive to the allergy causing substance through repeated and prolonged contact.
Repeated or single exposure to an allergen that results in the exposed individual becoming hypersensitive to the allergen.
A change in behavior or biological response by an organism that is produced by delivering a strong, generally noxious, stimulus.
An allergic response. Allergic responses to beryllium may indicate the onset of beryllium - related diseases.
It is possible to develop allergy-like reactions to some materials. In these cases, a person may become increasingly sensitive to a material after each exposure. Eventually, exposure to only small amounts of material may be needed to produce an allergic-type reaction of the skin or respiratory tract.
The process of developing an allergy.
an allergic response to an allergen that results in specific IgE antibodies being produced that allow allergic reactions whenever subsequent exposure occurs.
the development, over time, of an allergic reaction to a chemical.
Decreased threshold and/or increased response for a given stimulus due to increased sensitivity of the afferent ending
Repeated exposure to a foreign substance (antigen) that results in IgE production and makes the patient susceptible to an allergic reaction.
the initial exposure of an individual to a specific allergen, resulting in an immune response; further exposure usually induces a stronger response.
Progression in allergic reaction.
A simple form of learning in which an organism learns to strengthen its reaction to a weak stimulus if a threatening or painful stimulus follows.
Sensitization is an example of non-associative learning in which the progressive amplification of a response follows repeated administrations of a stimulus (Bell et al., 1995).
